Time to fork luaproc and turn it into an EFL based thing, with tighter integration into LuaSL.

More of this coming soon.

+/* This is a redesign of luaproc.  The design goals and notes -
+ *
+ * Use eina lists instead of the rolled your own lists.
+ *   Looks like a FIFO double linked list.
+ * Use ecore threads instead of raw pthreads.
+ *   Ecore threads pretty much wraps pthreads on posix, but has Windows support to.
+ * In general use EFL where it is useful.
+ * One fixed unique message channel per script.
+ *   Probably one fixed unique message channel per object, which each script in the object shares.
+ *   But might be better to handle that C side anyway.
+ * FIFO queue on message channels, seems the C socket queue is not enough.
+ *   On the other hand, could just peel messages the socket queue, then shove them on the scripts queue.
+ * Better integration with LuaSL.
+ *   Merge the luaproc structure with the script structure.
+ * Merge in the edje Lua code, and keep an eye on that, coz we might want to actually add this to edje Lua in the future.
+ * Use my coding standards, or EFL ones.  Pffft.
+ *
